Thread: Waking up with injuries sustained in your dream?

A few times over the course of my life, in my dreams I've been very angry at my brother, and when I finally try and attack him, I wake up as I jerk my arm, or kick my foot out.

A while ago, I had a dream where I wanted to punch him, and I woke up mid-swing as I punched the wall. My knuckles were bruised for a couple of days.
This kinda stuff can happen in light REM sleep, I think.

This happens to me repeatedly. I've dreamt of running through a forest, only to wake up with cuts that look like thorns had scratched my skin. I've dreamt of falling, only to wake up with a bruise just like the one from my dream. My feet will ache, like I've been running, when I was just fine before bed. It's irritating and amusing.
